Box Material

[Alwayslearningelec]

This box looks to list several different material. Hot dip gal, iron, steel etc. How is that possible?

 

[SceneryDriver]

Different parts of the box are made from different materials. It's spelled out in the data sheet:

The body is an iron alloy
The cover is steel
Gaskets are neoprene rubber
Cover screws are stainless steel
Mounting straps are steel

And then the body, mounting straps, and cover are dipped in molten zinc for the 'hot dip galvanized' finish.

The body is cast iron, not formed and welded, which itself offers corrosion resistance if the galvanizing is compromised, such as when you make a conduit penetration. Cast iron is also good for areas where impact may be a risk. The drawback is that to be strongest, it needs reinforcing angles and bosses. It’s difficult to do that on a simple flat lid, so the lid is stamped out of steel since you will not be making conduit entries into the lid. Then each part is dipped it molten zinc for galvanizing to further resist corrosion.

Not really, all these are ferreous metal, and are not electrically Dissimilar so that it would cause galvanic effect.
